' ELECTRIC CANDLE LAMP.

Application filed December 2a, 3920, serial Ho. eeavea. Renewed Sane e,

To all whom it may concem,

Be it known that l, MORDUCH L. KAPLAN, a citizen of the United States,and a resident of Brookl n, in the county of Kings and State of ew York,have invented certain new and useful Improvements in Electric CandleLamps, specification.

The invention pertains to the; class candle lamps possessing a batteryand an electric light bulb andadapted to stand on a table or the. like,said lamps being provided with a switch for making and breaking thecirthe battery and lamp, and the invention as for its purpose tosimplify and cheapen the cost of electric candle lamps and to providean-electric candle lamp comprising onl two units, to-wit: a battery anda detachab e cap or top member to be applied thereto and carrying thelamp bulb and switch. When the batte exhausted, the cap is removed terefrom and placed upon a new battery, thus restorin the candle lampforfurther use. In accor ance with my invention I dispense with theexpensive metallic casings which usually receive the battery of electriccandle lamps and provide a candle lamp consisting essentially and onlyof the battery and the detachable cap or dome-like top member, the

cap being e nipped with a socket to receive the lamp-bu band with aswitch for making and breaking the circuit. My invention may be carriedinto effect in several modified forms, and said invention and referredmeans embodying the same will he fully understood from the detaileddescription hereinafter presented, reference being had to theaccompanying drawings, in which: p

Fig. 14 is a corresponding view of a further modified embodiment of myinvention.

In the drawings, referring to Figs. 1 to 6 inclusive, illustrating myinvention, 20, 21 designate the cells of the. battery, which forconvenience, I will indicate as a whole by the numeral 22. The cells 20,21 are arranged as'usual, with the negative or zinc ole 23 of the upperbattery cell engaged with the carbon pole 24 of the battery cell belowit, and said cells 20, 21 in the com letion of the battery'are-enolosedin a pasteard cylinder or the like 25 which insulates and keeps thecells together and permits them to be handled as a single battery. 26'denotes the carbon pole of the upper batter cell 21, and it willpreferably be of the s ape shown, to-wit, having a lower neck portionand an upper head portion. The carton 25 enclosing the battery pluralcell battery before being applied one embodiment of 7 wra ping 27 an 22may be wrapped with an ornamental character ofpaper or the like 27 asafimsh for the candle lamp, which is broad enough at its lower end tostand securely upon a table and does not require the presence of theusual expensive metallic holderswith which electric table lamps arecustomarily rovided. I secure to the zinc of the lower battery cell 20 aconducting strip 28 which extends upwardl between the carton 25 and d?is bent over the upper end of t e battery cell 21 to form a convenientterminal 29, the carton 25 at the lower end of the strip 28 being cutaway, as shown in Figs. 1 and 2, to admit of the lower end of said stripbeing soldered to the zinc of the cell 20.

Upon the upper end of the battery 22 is attached aca or dome 30 whichsupports the features 0? my invention and which may be removed from onebattery and placed 'upon another'batter'y whenever occasion may sorequire.

The capor dome 30 may be of cast or sheet metal or of other suitablematerial, and at its lower edge is preferably flanged, as shown in Fig.1, to rest upon the upper edges of the carton 25and covering material27. In the present instance the dome or cap 30 is shown as formed ofcast metal and resting upon the terminal 29 of the conducting strip 28,said cap or dome being thus in electrical connection with the zinc ofthe battery cell 20. The cap or dome 30 is preferably of truncatedcone-shape so as to resemble approximately the upper end of theconventional form of a candle, the sides oftheycap or dome converging ongraceful linesupwardly and terminating in a sleeve portion 31. Withinthe cap or dome 30 I provide a vertical sleeve or cylinder 32 ofinsulating material, said sleeve being firmly gripped at its upper endwithin the contracted sleeve portion 31 of the cap or dome 30, while atits lower portion said sleeve 32 extends downwardly into approximatelynear relation to the upper end of the battery cell 21. Within the upperend of the sleeve 32 I provide a metallamp socket 33, said socket beingof cylindrical outline and threaded and tightly held within the upperend of the sleeve 32 in position to-recelve the terminal 34 of the lampbulb 35. Within the lower portion of a the sleeve 32 is provided aninverted sheet metal cap-like clutch 36 whose sides are slit to formspring members 37 which norsulating material 40 is interposed betweenthe bottom of thesocket 33 and top of the clutch member 36, and upon thelower end I of the screw 38 is provided a nut 41 for securing the partstogether. The screw 38 passes through a large opening in the bottom ofthe socket 33, and by not engaging said socket but engaging the fiberwasher 39 becomes insulated from said socket. The fiber washer 40insulates the socket 33 from the metalclutch member 36. The head of thescrew 38 forms an electric contact point for the lower terminal 420i thelamp 35, while the other terminal of said lamp is in electricalengagement with the socket 33. The ea or dome 30 carries the fibersleeve 32 and al of the parts connected therewith and, with said sleeveand its connections, may be handled as a unit and applied to and removedfrom the battery 22 at will.

In applying thecap or dome 30 and its parts to the battery 22 it is onlynecessary to shove the socket member 36 downwardly upon the head of thecarbon pole 26 of the battery, this action serving to properly locatethe lower edge of the cap or dome around the upper edge of the batteryand efiect the electrical connection of the cap or dome with theterminal 29 of the conducting strip-2.8. When the clutch member 36 isforced downwardly on the carbon pole 26 the head 43 on said pole 26becomes wedged within the clutch member 36 and forces the spring members37 outwardly against, the inner walls of the tube or cylinder, 32, or tothe position in which said spring members 37 are shown in Fig. 1. Theaction of the spring members 37 against the head 43 serves to detachablylock the cap or dome 30 and its parts upon the battery. The lamp bulb 35will be screwed into the socket 33, as usual, and said lamp bulb may bereplaced as often as may be required without removin the cap or dome 30from the battery.

pon the side of the cap or dome 30 I provide a slidable thumb-piece 44connected with a slidingswitch 45, whose upper end is disposed withinthe slot 46 cut in the side of the fiber sleeve 32. When the thumb-piece44 is pushed upwardly, the upper end of the switch 45 will engage theside of the lamp socket 33 and afford an electrical connection from thezinc of the battery cell 20 through the conducting: strip 28, cap ordome 30,

switch 45 and socket 33 to the terminal 34 of the lamp bulb, whence thecircuit will be from the terminal 42 of the lamp through the screw 38 tothe carbon pole 26 of the battery, this completing the circuit throughthe lamp and causing the latter to light. The circuit may be broken andthe light extinguished by sliding the thumbpiece 44 downwardly to removethe switch 45 from electrical contact with the lamp socket 33.

narrate The candle lamp shown in, Figs. 1 to 6 imelusive comprises twounitary parts, one being the battery 22 and the other the cap or domeand features carried by 1t. When the battery becomes exhausted the capor dome 30 maybe removed from it and laced upon a fresh battery. Thecandleam isv inexpensive of manufacture and easi y cared for andmanipulated, and said candle lamp may be set upon a table or can riedabout with the hand grasped upon the battery 22. I have also foundthatthe cap or dome 30 so tightly olin s to the battery that the entirearticle may e lifted by tak: ing hold of the cap or dome 30. The head 43on the positive pole 26 of the battery should be of such size so asto befirmly en- ,L'aged by the clutch member 36, and said head 43 may consistsimply of a metal cap driven upon the upper end of the pole mem-. ber26, sufficiently indicated in Fig. 13.

In my construction of candle lamp I employ as aforesaid two essentialfeatures, to-

Wit, the battery and the dome or cap 30, with its parts, and it is to beobserved that the cap or dome 30 is detachably connected with thebattery, and that in accordance with my invention I do nbt employ theexpensive metal parts at resent required in electric candle lamps. hecovering material 27 on the battery will be made sufiiciently attractiveto cause the candle lamp to have an ornamental appearance, and saidcovering material may be of paper,- linen or other convenient material.

In Figs. 7, 8 and 9 I illustrate a modified construction of myinvention, and in these figures 46 denotes-the battery, 47 the dome orcap therefor and 48 the lamp bulb, which is held in a metallic threadedlamp socket 49 soldered within the upper contracted end portion 50 ofthe cap or dome 47. The cap or dome 47 has secured to its lower flan dedge, where it rests on the battery 46, a h re ring51 and a1 fibre disk52 which has an open center, as at 53, and i'scut out at one side, as

at 54, to expose the free end of a switch spring 55 secured by rivets tothe upper face of the fibre washer 52, said free end of the switchspring 55 being directly over and flanged downwardly to permanentlyengage a terminal 56 formed by bending inwardly over the battery theupper end of a conducting strip 57, which corresponds with theconducting strip 28 of Fig. land at its lower end will be connected withthe zinc or negative pole of the battery correspondingly with theconstruction shown in Fig. 1. socket 49 has secured to its lower portiona fibre or other insulating tube 58 and within the lower end of thistube 58 is secured the invert-clutch member 59 which corresponds withthe clutch-member 36 of Figs; 1 to 6 of sheet-metal and having to beforced uponthe;

inclusive, being spring members 60 lamp, 69

The lamp the battery. The clutch-member 59 is connected with thelamp-socket 49 by means of a screw 61 whose head is engaged by the lowerterminal of the lamp-bulb and whosev 43 of the posilowerend engages thehead tive pole element 26 of the battery, an insu lating washer 62 beingprovided below the head of the screw and an insulating washer 63 beinprovided between the lamp socket 49 and c utch-member 59, said screw andinsulating washers corresponding with, the construction shown in Figs. 1and 5. Upon the side of the cap or dome 47 is rovideda turn-button orhead 64 mounts on a pin 65 which has a bearing in the side of the cap ordome 47 and at its inner end carries an arm 66 which, when turneddownwardly will engage the switch-spring 55 which is against theterminal 56 to complete the circuit through the batter and lamp andwhich, when turned from said spring 55, will break the circuit. Thecircuit pole of the 57, switch-spring 55, arm 66, cap or dome 47 and lam-.socket 49 to one terminal of the lamp an from the other terminal ofthe lamp throu h the screw 61 to the positive pole of the attery.

is from the ne ative The cap or dome 47 with all of its own features maybe detached from and applied to the battery in the same manner that thebattery through the con uctor Y cap or dome carrying the features to bea plied to the battery for producing a cand e the lamp bulb and 70 afibre or other insulating tube held at'its upper end by the lampsocketset within the contracted neck portion 71 of the cap or dome 68, said Itube 70 corresponding exactly with the tube 58 shown in Fig. 7; Thefibretube 70 contains the lamp socket 49, clutch-member 59, screw 61 andfibre washers 62, 63 exactly as shown in Fig. 7 and therefore notfully'illustrated in Figs. 10 and 11. The clutchmember in Figs. 10 and11 isshown at 72 and engages the positive pole element 73 of the battery67. The screw of Fig. 11 corresponding with the screw 61 of Fig. 7, ll

number 74;

' Upon the lower flanged edge of the cap or dome 68 is secured a fibrering or washer 75, and to this ring or washer is secured a slittedconductingdisk-like plate 76 having a series of inwardly and downwardlyextendllllii in main spring-sections 7': some one or w ich will, whenthe cap or dome 68 is applied upon the battery, engage the upper] springcontact sections 77 .will engage the terminal 78. Th purpose: of havinthe ring of contact sections 77 is to make 1t unnecessary to use anyspecial care in applying the cap or dome 68 upon the battery. Thecircuit is made from the .slitted ring or plate 76 .up through the capor dome 68 to the lamp socket by means of a push-button or slide 80whose stem. passes through a slot' 81in the cap or dome 68 and carrieson its inner end a conducting arm 82 adapted, when the slide 80 is moveddownwardly to the lpo-- sition shown in Fig. 10, toenter into e e tricalengagement with the ring or plate 76,

thereby to make the circuit from the conductingstrip 79 to the lampsocket. When the slide 80 ispushed upwardly on the side of the dome orcap 68, the arm 82 will be carried from the plate or ring 76 and thecircuit will be thereby broken.

Fig. 13 presents an embodiment of my mvention in which the circuit ismade and broken by a rotary movement of the cap or pole element, and 91.a screw connecting the lamp-socket 88 with the cap 90 and which is incircuit with the lower terminal of the lamp and said cap, a fibre washer92 being being provided within the socket 88 below the head of the screw91 and a fibre washer 93 being interposed between the lower end of saidsocket 88 and a nut 94 provided on the screw 91 and firmly engaging saidwasher 93. 'The lower threaded end of the screw 91 enters a threadedhole in the cap 90. When the ,cap or dome 86 is rotated to work thescrew 91 downwardly throu h the cap 90, the lower flanged edge of t edome will be pressed against the upper bent end of the conducting strip84 and at that time the circuit will be from the strip 84 through thedome 8'6 and lamp socket 88 to one terminal of the lamp 87 and thencethrough the lower terminal of said lamp, screw 91 and cap 90 to thepositive pole or element 89 of the battery. When the dome the positivelower flang is moved against the up r end portion of fitting upon andpreferably not detachable from said positive 86 is reversely rotated,the cap or dome will be elevated by reason of the enga ment of the screw91 with the cap 90 an this will result in the lower flanged edge of thecap or dome leaving the conducting strip 84 and in the breaking of thecircuit.

In Fig. 14 I illustrate a further embodiment of my invention in whichthe circuit is made and broken by a rotary movement of the cap or dome,and therein 95 designates the battery, 96 the usual conducting stripthereof, 97 the u r terminal of said strip extending inwar y over thebattery, 98 the metallic cap, or dome, 99'the lamp, 100 the threadedlamp socket secured within the upper contracted end of said dome, 101 athreaded positive pole element or screw at the upper end of the batte102 amp or the like mounted upon an engaging the thread of said screw,and 103 the screw connecting the lamp socket 100 with the cap 102, afiber washer 104 being interposed below the head of said screw and afiber washer 106 being interposed between the lower end of the'lampsocket 100 and the upper end of the cap 102. In the construction shownin Fig. 14, when the cap or dome 98 is retated' to work the cap 102downwardly on Io element or screw 101, the edge of the cap or dome 98the strip 96 and the circult will then be completed through the batteryand lamp. When the cap 01. ome 98 is, reversely rotated it will, byreason of the engagement of the cap 102 with the screw 101, becomeelevated from the conductin strip 96, and thereby the circuit through te lamp .will be broken.

' In Fig. 13 the screw 91, on the rotation of the cap or dome 86,effects the movement of said cap or dome 86 to make or break thecircuit, and in Fig. 14 the rotation of the cap or dome 98 efi'ects themaking or breaking oi the circuit due to its depression or elevation bythe action of the screw 101.

It will be understood from the foregoing description that several formsof make-andof Fig. 13 is allowed to remain in its lower position againstthe terminal 85, the circuit may be broken by turning the lamp 87 tomove upwardly and carry its lower terminal from the screw 91, thusextinguishing the li ht, and said circuit ma. be again esta lishedwhenever desired y screwing the lamp 87 downwardly until its lowerterminal again engages the screw 91. -I may therefore use the lamp-bulbas a make-and-break switch. In the construction shown in Fig.

j 14, the lamp bulb may v tion, and

neonate also, h employed for makin and breaking the circuit. Iii-all ofthe forms of my invention "hereinbeforedescribed I employ batteries ca aand a remova 1e ble or standing on on the lamp cap or domecarrying andother features adapting it, in connection with the to create a suitablecandle lamp.-
